26. -9x-4y
27. 30+6x
28. 5a+6

30. -8x+10

Explanation:

Hopefully I'm right,but what you do is add the ones with variables together so

Question 15

3a + 2 + 3a + 7

so 3a+3a= 6a and 7+2=9

so you have to add the ones that are similar but never add

3a+7 because they are not the same

37. 5x-2y

38. -3a+2b
